Own made clock

2017-01-10 fash

We made our own nerdy clock.

We took a big clock and covered the backplane with modeling grass.

It took about 5 containers to fill the backplane enough to get it nicely filled.

The lettering near the pictures are the RGB representation of the color used in our office.

Lets see if you can decode them all. (use password clock to view solutions!)

Beer glasses

2016-11-12 fash

I’ve collected some beer glasses in the past, but i didn’t have many.
I hated the fact that your are not using them OR (even worse).
Put a different brand of beer in the branded glass!

So i bought a set of these:

I like the no-brand no-logo … just-a-glass look.

So why different types of glasses. Some say “nonsence!”

Welllll .. maybe for a part.
Click on the images for more information about the glass.
Below i will use the names of the glasses, these are NOT generally accepted names.

Some types of glasses like the “Breughel” concentrate the aroma.
A heavy stout mostly has less volume, it looks weird in a pint glass.
Besides the volume, a lighter beer looks better in a “Prague” glass
Some glasses are better suited for keeping the beer cold, other you can warm a little in your hand.
( Beer is NOT always best cold! When you drink it too cold, you will numb your taste buds. Most beerbottles have a temperature suggestion)
Bulb glasses like “Grand Cru” will keep your foam longer.

There is no need for a foam head on your stout, so use a “Gusto” for example.

Temperatures (a little example) Do your research on the internet!

4 degrees celsius : Light lagers, Pilsners
7 degrees celsius : Blondes, Wheat and Hefeweizen
10 degrees celsius : Red, Amber, IPA, Tripple
12 degrees celsius : Bitters, Scotch Ale, Stouts and Porters
14 degrees celsius :Imperial Stouts, Double bock, Barley Wines, Milk stouts

Stabilise and speedup movie – Death road Bolivia

2016-08-12 fash

This year we spend our vacation in Peru and Bolivia with Arja. (20160606-20160704)

We did the Death road in Bolvia, wellll Arja and me. Coline fell ill the day before.

I tried to get a sense of what it was using a action cam mounted on my helmet and speeding it up in afterprocessing.
Shamefully i have to admit, that most of the times my camera was recording my frontwheel ..

To post: script/program to create this effect

This movie has been stabilized and sped up.

See https://en.wikipedia.org/wiki/Yungas_Road for more information.

Starting at 4700 meters and on the good parts going down @70km/h. Then the dangerous parts started. Feeling like ‘offroad’ narrow corners, where you can expect to see a minivan coming around the corner anytime. Steep drops without barriers. Water and land slides.

Nikon Lenses

2016-07-28 fash

Created a graph for my Nikon lenses. It shows me what lens i can use at what Aperture / Range.

( https://media.henriaanstoot.nl/websites/lenses/ )

It uses canvas to draw lines and text, but thats only interesting for static stuff. ( https://www.w3schools.com/graphics/canvas_drawing.asp )
My example uses a php script to load information from a csv file. And loops though those entries and draw lens info.

Piece of canvas script to draw 17-70mm lens info.

ctx.fillStyle = 'rgba(0, 200, 100, 0.9)';
ctx.lineWidth=2;
ctx.beginPath();
ctx.moveTo(189.98560128675,163.25813588993);
ctx.lineTo(359.81942904592,202.49237972319);
ctx.lineTo(359.81942904592,250);
ctx.lineTo(189.98560128675,250);
ctx.strokeStyle="rgba(0,0,0,0.9)";
ctx.closePath();
ctx.fill();
ctx.stroke();
ctx.fillStyle = 'rgba(0,0,0,0.9';
ctx.save();
ctx.translate( 189.98560128675,153.25813588993);
ctx.rotate(-Math.PI / 4);
ctx.fillText("17-70mm", 0,0);
ctx.restore();
